China's basic national condition is a large population with limited arable land. With the adjustment of the country’s food policy, converting limited farmland into pasture or for raising geese is not practical for farmers. Therefore, actively developing a grass-and-grain-saving goose industry has become an important direction in the structural adjustment of animal husbandry. Below are some conservation-oriented techniques for raising geese.
Geese and goslings are grazing poultry that require a significant amount of green feed and roughage during their growth. Green feed serves as their main nutritional source. Therefore, areas such as hillsides, grasslands, farmlands, ditches, and even wild pastures along roads can be utilized. Weeds like eucalyptus, bitter leeks, dandelions, cornflowers, and other wild plants can be used as feed. These weeds are not only rich in nutrients but also less contaminated, helping to save grain. Goose farmers typically buy young geese in spring and summer. After one week of age, they start grazing in the late afternoon and are fed in the evening. They are usually sold in autumn and winter. Each goose consumes only 4–5 kg of feed and can generate over 15 yuan in profit. In my region, some farmers raise about 500 geese per batch using riverbank leeches, weeds, and wild hummus, achieving good economic returns.
Another method involves raising wheat geese. When geese graze in wheat fields, they feed on wheat leaves and weeds without affecting the growth of the wheat. This practice provides sufficient feed for geese while promoting both grain and poultry production. Raising 40–60 geese per mu can yield 600–900 yuan in profit. Key points include:
- **Choosing suitable breeds and wheat varieties**: Breeds like four-season geese, Longchang geese, and Yangzhou geese are preferred for their hardiness and fast growth. Wheat seeds should be selected based on local climate and soil conditions.
- **Proper sowing**: Sow wheat 7–10 days earlier than usual to ensure enough leaves for geese. Increase the seeding rate by 1.5–2.0 kg per acre.
- **Fertilization**: Apply 8 kg of urea before and after December 20th and January 20th to promote early growth. After late February, stop grazing during wheat jointing and apply 10 kg of urea per acre. Ensure proper restoration of wheat seedlings to achieve dual growth.
- **Grazing management**: Purchase goslings at around 50 per acre in mid-to-late December. Keep them indoors for 20 days before gradually introducing them to the fields. Divide the field into sections for rotational grazing. Train geese to move in a "one-for-one" formation. Feed them compound feed at night, including bran, grains, 1.5% bone meal, 2% shell powder, and 0.3% salt to support healthy bone development.
Another model is the **Linyuan goose system**, which uses orchards or undergrowth areas without occupying arable land. Geese graze on weeds, not on leaves or bark, making it a pollution-free ecological model. There are three types:
- **Deciduous forest geese**: In fruit forests, ryegrass can be sown annually in autumn. Geese are raised in spring, grazing on ryegrass and then on forest weeds. Their droppings enrich the soil, allowing year-round raising.
- **Evergreen forest geese**: Primarily feed on wild weeds. Shade-tolerant plants like white clover can be sown to supplement feed.
- **Young forest geese**: Use small trees and sunny areas with grasses like ryegrass and red clover. Two methods are commonly used.
Regardless of the model, appropriate supplements must be provided to meet the nutritional needs of geese. During fruit tree growth periods, feeding should be paused. For large forest areas, building sheds within the forest can reduce land use and improve management.
Lastly, **straw geese** involve using crop residues like corn stalks, hawthorn vines, peanut vines, and other plant parts. These are processed into silage or grass powder and mixed with concentrates to raise geese.
In conclusion, choosing the right local method for raising geese is key to achieving good results. By adapting these techniques, farmers can efficiently utilize available resources while promoting sustainable development.
Hematology Analyzer
Hematology analyzer is also called clinical blood cell analyzer, blood cell analyzer, blood cell analyzer, blood cell counter. The blood analyzer not only improves the accuracy of the experimental results, but also provides many experimental indicators, which play an important role in the diagnosis and differential diagnosis of diseases. Hematology analyzer is one of the most widely used instruments in hospital clinical testing.
Test items
Blood cell test refers to routine blood test, which is manual operation and counting under the microscope at first. It includes red blood cell, hemoglobin, white blood cell count and its classification, platelet count, etc. There are more than 20 items.
clinical significance
1. The blood analyzer is mainly used to detect various blood cell counts, white blood cell classification and hemoglobin content.
2. Hematocrit: obtained by multiplying the average volume of red blood cells by the red blood cell count.
3. Red blood cell distribution width: represents the degree of consistency of red blood cell size. When the red blood cell size is uneven, the red blood cell distribution width value increases, such as various types of nutritional deficiency anemia.
4. The three average indices of red blood cells are used to identify the type of anemia.
(1) The average hemoglobin content of red blood cells: increased in megaloblastic anemia, decreased in iron deficiency anemia, chronic blood loss anemia, uremia, chronic inflammation.
(2) Mean volume of red blood cells: increase in hemolytic anemia and megaloblastic anemia; decrease in severe iron deficiency anemia and hereditary spherocytosis.
(3) The average red blood cell hemoglobin concentration: decrease in chronic blood loss anemia, iron deficiency anemia; various diseases can be in the normal range. In megaloblastic anemia, the mean red blood cell volume increases, the mean red blood cell hemoglobin amount increases, the mean red blood cell hemoglobin concentration is normal, and the red blood cell distribution width increases.
5. Average platelet volume: the average volume of each platelet, the size of platelets is related to its function.
(1) Increased: seen in patients with idiopathic thrombocytopenic purpura, edema and proteinuria in late pregnancy.
(2) Decreased: seen in non-immune platelet destruction, aplastic anemia, thrombocytopenia repeated infection syndrome, chronic myeloid leukemia, etc.
